Answer : The wrong equation is, K_p=K_c\times (RT)^{-5}

Explanation :

The given equilibrium reaction is,

4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)

The expression for equilibrium constant in terms of concentration,

K_c=\frac{1}{[O_2]^3}\\\\K_c=[O_2]^{-3}

The expression for equilibrium constant in terms of pressure,

K_p=\frac{1}{(P_{O_2})^3}\\\\K_p=(P_{O_2})^{-3}

The relation between the equilibrium constant in terms of concentration and equilibrium constant in terms of pressure will be,

K_p=K_c\times (RT)^{\Delta n_g}

where,

\Delta n_g= number of moles of gaseous products - number of moles of gaseous reactants

R = gas constant

T= temperature

For reaction the given reaction,

\Delta n_g= number of moles of gaseous products - number of moles of gaseous reactants= 0 - 3 = -3

K_p=K_c\times (RT)^{-3}

Therefore, the correct equations for equilibrium are, K_c=[O_2]^{-3}, K_p=(P_{O_2})^{-3} and K_p=K_c\times (RT)^{-3}

Using data from Ms.Baltzers students, they found the mass of a piece of brown metal was 14.2 grams, and the volume of that same
Hunter-Best [27]

Answer:

d = 7.9 g/mL

Explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

Mass of brown metal = 14.2 g

Volume = 1.8 mL

Density = ?

Solution:

d = m/v

d = 14.2 g/1.8 mL

d = 7.9 g/mL

The spontaneous reaction that occurs when the cell in the picture operates is as follows: 2Ag+ + Cd(s) ???? 2 Ag(s) + Cd2+ (A) V
Snowcat [4.5K]

Answer:

14. B    15. D    16. C     17. B

Explanation:

The spontaneous reaction that occurs when the cell operates is shown below:

2Ag^{+} + Cd_{(s)} ⇒2Ag_{(s)} + Cd^{2+}

We need to select the correct option from the list below for the following questions.

(A) Voltage increases. (B) Voltage decreases but remains > zero. (C) Voltage becomes zero and remains at zero. (D) No change in voltage occurs. (E) Direction of voltage change cannot be predicted without additional information.

14. A 50-milliliter sample of a 2-molar Cd(NO_{3})_{2} solution is added to the left beaker.

If a 50-milliliter sample of a 2-molar Cd(NO_{3})_{2}  solution is added to the left beaker, the voltage decreases but its value remains greater than zero. The correct option is B

15. The silver electrode is made larger.

If the silver electrode is made larger, no change in the value of the voltage since we don't have the idea of the initial value. The correct option is D.

16. The salt bridge is replaced by a platinum wire.

If the salt bridge is replaced by a platinum wire, there will be no passage of electrons because electrons can't pass through a platinum wire. Therefore, the voltage will be zero and remains at zero. The correct option is C.

17. Current is allowed to flow for 5 minutes.

If current is allowed to flow for 5 minutes, the voltage decreases but its value remains greater than zero. The correct option is B.
